Description

Technical Field

[0001] The present invention particularly relates to an outdoor elevator mounting frame. Background Art

[0002] With the continuous improvement of people's living standards and the change of residents' concepts, there is a great demand for installing elevators in old buildings. For residents living on high floors, especially the elderly, this will be a significant change. Installing an elevator can well solve the time required for them to go up and down the stairs. However, in the original old buildings, it is impossible to design elevator hoistways. Therefore, we can only complete this project outside the old buildings. Some existing outdoor hoistways generally use steel structure derricks covered with protective plates, which are simple in structure, practical and economical.

[0003] Most of the existing outdoor elevator hoistway steel frames are connected and fastened by bolts that lock the columns and crossbeams. However, using the above method, once the bolts become loose due to aging, the crossbeam will directly fall, causing a risk of injury and not meeting the usage requirements. Summary of the Invention

[0004] Aiming at the defects existing in the above-mentioned prior art, the technical problem to be solved by the present invention is: to provide an outdoor elevator mounting frame.

[0005] An outdoor elevator mounting frame includes a top frame and four columns. An installation space for installing an elevator hoistway is formed between the top frame and the four columns. Connecting crossbeams are provided between adjacent columns. A limiting component is provided between the columns and the connecting crossbeams. On both sides of the column that are in contact with the connecting crossbeam, a number of U-shaped through holes are respectively provided at intervals in the vertical direction. Through the U-shaped through holes, positioning flap plates that can be folded under force are formed on the inner side. The positioning flap plates can be folded and correspondingly support and abut against the lower side of the connecting crossbeam.

[0006] In an embodiment, the limiting component includes a first limiting block that is horizontally telescopically and movably arranged on the side wall of the column, a driving member for driving the first limiting block to protrude outward from the side wall of the column, and a second limiting block that is vertically movably arranged at the end of the connecting crossbeam. The first limiting block has a first limiting groove recessed on the side opposite to the column. One end of the connecting crossbeam is fitted into the first limiting groove. The lower side surface of the first limiting groove is a guiding inclined surface. A second limiting groove that can be fitted with the second limiting block is recessed on the upper side of the first limiting groove. The guiding inclined surface can abut against the lower end of the second limiting block so that the upper end of the second limiting block is fitted into the second limiting groove.

[0007] In one embodiment, a first cavity with an opening on one side is formed inside the upright column. A screw rod vertically arranged is provided inside the first cavity. The driving member is threadedly sleeved on the screw rod. The lower side surface of the driving member is a guiding conical surface inclined along the circumference. One end of the first limiting block abuts against the guiding conical surface. A spring is abutted between the inner side of the first cavity and the first limiting block, so that one end of the first limiting block is kept tightly abutted against the guiding conical surface by the spring.

[0008] In one embodiment, the upright column is formed by bending a steel plate. The first cavity is formed inside the upright column. A plurality of first reinforcing rib plates are vertically arranged at intervals inside the first cavity. The positioning flap can be folded and respectively and correspondingly support and abut against the lower sides of the first reinforcing rib plates. The first reinforcing rib plates are welded and connected to the side walls of the first cavity along the edge contours.

[0009] In one embodiment, connecting plates are respectively arranged on both sides of the opening of the first cavity on the upright column. The top frame has an installation cavity with a lower opening. The four upright columns are respectively distributed at the four corners of the installation cavity. The connecting cross beam is detachably connected between the adjacent connecting plates of different upright columns through bolts, and the connecting cross beam is detachably connected to the inner side wall of the installation cavity through bolts.

[0010] In one embodiment, a plurality of first through holes and a plurality of second through holes are vertically and alternately arranged at intervals through the upright column. The plurality of first through holes and the plurality of second through holes are vertically arranged in a one-to-one corresponding and staggered manner. The first through holes and the second through holes are respectively communicated with the first cavity. A first convex portion and a second convex portion are arranged at intervals up and down on one side of the first limiting block. The first convex portion is movably inserted into the first through hole, and the second convex portion is movably inserted into the second through hole. The first limiting groove is formed between the first convex portion and the second convex portion.

[0011] In one embodiment, a second cavity with an opening on one side is formed inside the connecting cross beam, and the second cavity penetrates through both ends of the connecting cross beam. The positioning flap can be folded into the second cavity and support and abut against the connecting cross beam.

[0012] In one embodiment, a plurality of second reinforcing rib plates and a plurality of third reinforcing rib plates are detachably connected between the top frame and the connecting cross beam through bolts. The length direction of the second reinforcing rib plates and the length direction of the third reinforcing rib plates are arranged in a 90-degree splicing manner.

[0013] In one embodiment, the cross sections of the second reinforcing rib plates and the third reinforcing rib plates are both U-shaped, so that wire routing cavities are respectively formed inside the cavities of the second reinforcing rib plates and the third reinforcing rib plates.

[0014] In one embodiment, a plurality of first mounting holes are vertically arranged at intervals on the connecting plate. The connecting cross beam is provided with second mounting holes corresponding to the first mounting holes. Bolts are inserted and matched between the first mounting holes and the second mounting holes.

[0016] The present invention can effectively avoid the risk of the connecting cross beam directly falling and injuring people when the bolts connecting the connecting cross beam and the column become loose through the limiting component;

[0017] Moreover, when the connecting cross beam and the column are butt - joint installed, by applying force to the positioning flap by the installer, the positioning flap can be folded relative to the column. When the positioning flap is folded to a state where it can abut and support the connecting cross beam, when the positioning flap abuts and supports the connecting cross beam, the connecting holes for the bolts to be inserted between the connecting cross beam and the column are arranged in alignment. Thus, the alignment of the connecting holes between the column and the connecting cross beam is facilitated through the positioning flap, thereby facilitating the installation by the installer.

[0024] The present invention will be further described below in conjunction with the drawings and the detailed description:

[0025] As Figures 1 to 6As shown, the embodiment of the present invention preferably provides an outdoor elevator mounting frame, including a top frame 1 and four columns 2, an installation space for installing an elevator shaft is formed between the top frame 1 and the four columns 2, a connecting beam 6 is provided between adjacent columns 2, a limiting assembly 99 is provided between the columns 2 and the connecting beam 6, and a plurality of U-shaped through holes 8 are respectively penetrated along vertical intervals on both sides of the columns 2 for abutting against the connecting beam 6, and a positioning flap 9 that can be folded under force is formed on the inner side of the U-shaped through hole 8, and the positioning flap 9 can be folded and correspondingly supported against the lower side of the connecting beam 6.

[0026] Specifically, the limit assembly is used to effectively prevent the risk of the connecting beam falling directly and hitting or injuring people when the bolts connecting the connecting beam and the column are loosened; and when the connecting beam and the column are docked and installed, the installation worker applies force to the positioning flap to fold the positioning flap relative to the column, and the positioning flap is folded to a connection state where it can abut against the supporting connecting beam. When the positioning flap abuts against the supporting connecting beam, the connecting holes for bolt insertion between the connecting beam and the column are arranged in alignment, and then the positioning flap is used to facilitate the alignment of the connecting holes between the column and the connecting beam, thereby facilitating the installation of the installation worker.

[0027] Preferably, the U-shaped perforation on the column is arranged horizontally, that is, after the column is installed upright, the force bending direction of the positioning flap is inclined at 90 degrees to the gravity direction, and the positioning flap is folded horizontally relative to the column and supported on the lower side of the first reinforcing rib plate.

[0028] Furthermore, the limiting assembly 99 includes a first limiting block 21 which is movably arranged on the side wall of the column 2 in a transverse telescopic manner, a driving member 22 for driving the first limiting block 21 to remain protruding from the side wall of the column 2, and a second limiting block 23 which is movably arranged at the end of the connecting beam 6 in an up and down manner. The first limiting block 21 is located on the side opposite to the column 2 and is concave with a first limiting groove 24. One end of the connecting beam 6 is embedded in the first limiting groove 24. The lower side surface of the first limiting groove 24 is a guide bevel 25. The upper side of the first limiting groove 24 is concave with a second limiting groove 26 which can be embedded with the second limiting block 23. The guide bevel 25 can abut the lower end of the second limiting block 23 so that the upper end of the second limiting block 23 is embedded in the second limiting groove 26.

[0029] Specifically, the driving member in the limiting assembly drives the first limiting block to maintain a state of protruding outward from the column, and further, the first limiting groove of the first limiting block maintains an engaged connection state with the connecting cross beam. At this time, the second limiting block in the connecting cross beam is abutted by the guiding inclined surface of the first limiting groove, causing the second limiting block to move upward relative to the connecting cross beam and engage in the second limiting groove within the first limiting groove, thereby achieving complete limiting of the first limiting block and the connecting cross beam, effectively avoiding the risk of the connecting cross beam directly falling and causing injury when the bolts connecting the connecting cross beam and the column become loose.

[0030] Further, a first cavity 3 with an opening on one side is formed inside the column 2. A vertically arranged screw rod 27 is provided in the first cavity 3. The driving member 22 is threadedly fitted over the screw rod 27. The lower side surface of the driving member 22 is a guiding conical surface 28 inclined along the circumference. The guiding conical surface 28 abuts against one end of the first limiting block 21. A spring 29 is abutted between the inner side of the first cavity 3 and the first limiting block 21, so that one end of the first limiting block 21 is kept tightly abutted against the guiding conical surface 28 by the spring 29.

[0031] Specifically, in the initial state, the first limiting block is in a contracted state relative to the column under the elastic force of the spring. At this time, one end of the first limiting block is kept tightly abutted against the guiding conical surface of the driving member. After the connecting cross beam is displaced and its end is aligned with the first limiting groove of the first limiting block, the driving member is then screwed to make the driving member move downward along the screw rod. As the driving member moves downward, the guiding conical surface on the driving member abuts against one end of the first limiting block, and then the first limiting block is displaced relative to the column through the guiding of the guiding conical surface, causing the first limiting block to be in a state of protruding outward from the side wall of the column. The first limiting groove of the first limiting block maintains an engaged state with the connecting cross beam, and through the guiding inclined surface of the first limiting groove, the second limiting block is kept in an engaged state in the second limiting groove, realizing a firm connection between the connecting cross beam and the column. Then, the installer can install connecting bolts between the connecting cross beam and the column to make the connection between the connecting cross beam and the column more firm.

[0032] Further, the column 2 is formed by bending a steel plate. The first cavity 3 is formed inside the column 2. A plurality of first reinforcing rib plates 7 are vertically arranged at intervals in the first cavity 3. The positioning flap 9 can be folded and correspondingly supported and abutted against the lower side of the first reinforcing rib plates 7. The first reinforcing rib plates 7 are welded to the side wall of the first cavity 3 along the edge contour.

[0033] Specifically, the column is formed by bending a steel plate to effectively save the materials and processing production costs of the column. The first cavity is formed inside the column, and then a plurality of first reinforcing rib plates are welded vertically at intervals in the first cavity to effectively ensure the structural strength of the column formed by bending the steel plate.

[0034] During actual operation and installation, by pre-placing a number of first reinforcing rib plates in the first cavity of the column, at this time, the first reinforcing rib plates can reciprocally move along the length direction of the column relative to the first cavity. The installer manually moves the first reinforcing rib plates. When the first reinforcing rib plates are displaced to the position where they need to be welded to the column, the installer applies force to the positioning flap so that the positioning flap folds relative to the column. The positioning flap folds to a connection state where it can abut and support the first reinforcing rib plates. Furthermore, the welding support positioning of the first reinforcing rib plates is achieved through the positioning flap, effectively avoiding the drawback that it is difficult to position and support the welding of the first reinforcing rib plates on the column after the column is vertically installed and fixed.

[0035] Furthermore, on the column 2 and on both sides of the opening of the first cavity 3, connecting plates 4 are respectively provided. The top frame 1 has an installation cavity 5 with a lower opening. Four columns 2 are respectively distributed at the four corners of the installation cavity 5. The connecting cross beam 6 is detachably connected between adjacent connecting plates 4 of different columns 2 through bolts, and the connecting cross beam 6 is detachably connected to the inner side wall of the installation cavity 5 through bolts.

[0036] Specifically, the connecting cross beam is connected between the connecting plates of different columns through bolts, and through the connecting cross beam, the mutual locking between adjacent columns is effectively achieved. The connecting plates of the column adopt the method of bending and turning outwards at the opening of the first cavity, so as to facilitate the locking connection of the bolts between the connecting plates and the connecting cross beam.

[0037] Furthermore, the column 2 vertically penetrates through a number of first through holes 31 and a number of second through holes 32 at intervals. The number of first through holes 31 and the number of second through holes 32 are arranged in a staggered manner vertically in one-to-one correspondence. The first through holes 31 and the second through holes 32 are respectively communicated with the first cavity 3. On one side of the first limiting block 21, a first convex part 33 and a second convex part 34 are arranged at intervals up and down. The first convex part 33 is movably inserted into the first through hole 31, the second convex part 34 is movably inserted into the second through hole 32, and the first limiting groove 24 is formed between the first convex part 33 and the second convex part 34. Furthermore, a guiding inclined surface is formed on the upper side of the second convex part, and a second limiting groove is formed on the lower side of the first convex part. The guiding inclined surface and the second limiting groove are arranged oppositely.

[0038] Furthermore, the connecting cross beam 6 has a second cavity 10 with an opening on one side, and the second cavity 10 penetrates through both ends of the connecting cross beam 6. The positioning flap 9 can fold into the second cavity 10 and abut and support against the connecting cross beam 6. Furthermore, the positioning flap can fold relative to the column into the second cavity of the connecting cross beam to achieve the hidden effect of the positioning flap and avoid the installation interference caused by the positioning flap being externally placed outside the connecting cross beam.

[0039] When the positioning flap abuts against and supports the connecting cross beam, the connecting holes for bolt insertion between the connecting cross beam and the column are arranged in alignment at this time. Further, the positioning flap facilitates the alignment of the connecting holes between the column and the connecting cross beam, thus facilitating the installation by the installers. The positioning flap plays a role of positioning and limiting.

[0040] Further, a plurality of second reinforcing plates 11 and a plurality of third reinforcing plates 12 are detachably connected between the top frame 1 and the connecting cross beam 6 by bolts. The length direction of the second reinforcing plates 11 is spliced with the length direction of the third reinforcing plates 12 at 90 degrees. Further, the structural strength of the overall steel frame is effectively enhanced by the plurality of second reinforcing plates and the plurality of third reinforcing plates.

[0041] Further, the cross sections of the second reinforcing plates 11 and the third reinforcing plates 12 are both U-shaped, so that wire routing cavities are respectively formed in the inner cavities of the second reinforcing plates 11 and the third reinforcing plates 12. Further, the wire routing cavities facilitate the routing of cables.

[0042] Further, a plurality of first mounting holes 13 are arranged at intervals along the vertical direction on the connecting plate 4. The connecting cross beam 6 is provided with second mounting holes 98 corresponding to the first mounting holes 13. Bolts are inserted and matched between the first mounting holes 13 and the second mounting holes 98.
